The TE 350 and new EXC 400 seem to be a compromise at best. As an ageing (heavy) warrior I no longer get the best from my 450. A 310 is really a 250 on roids, certainly a little punchier in the bottom to mid part of the curve. However a cure for many would be a dedicated 350. I have had these discussions with my mates unfortunately they atr part of the unwashed masses and ride KTM's and Yammy's however the consensus is that a 350 would best suit all of our needs. Egos would also forestall us going under 350cc's anyway. Is there any chance of Husky looking at this logical step between 250's and 450's.
My riding buddies and I have had the same talk over here. We agree that would be the best of both worlds. The TXC 310 is really, really good though. I have not heard of Husky doing that although I think the standard Husky 250 four stroke could handle it if Athena built it. I would not hold your breath for Husky to do so though. With the new motor 250 around the corner I read in Motocross digital that they did consider as far as a 300 with the new one.
